Optimum climate conditions: Drying pellets

Operators of pellet boilers set great store by a good fuel quality. By use of the high-performance desiccant dehumidifiers from Trotec pellets are protected from the harmful humidity during production and storage.

Who turns his back on proper air conditioning for production and storage facilities risks serious damage to the product. This is also true for the manufacturing of pellets. The biofuel is particularly susceptible to excessive humidity values. For the untreated raw wood withdraws the humidity from the air and absorbs it. With devastating consequences for both the customer and the manufacturer: Because the formation of mould stains and mildew is imminent. The machines in the processing facility also suffer from the moisture exposure and begin to corrode. It usually pays to invest in a technical upgrade so as to retain the pellet quality and to protect the production machines. The stationary desiccant dehumidifiers of Trotec’s TTR series efficiently and reliably extract moisture from the ambient air. 

Inexpensive, efficient and eco-friendly: This would be the textbook example of modern-day heat supply. Which is why pellet boilers are in great demand for new buildings, but also when it comes to a conversion to regenerative heating media. Pellets can be used for heating without hesitation and the customer is independent from the price developments of oil and gas. As a matter of fact pellets are fundamentally a by-product in the woodworking industry. Whilst tree trunks are cleared for further processing in sawmills, the pellet manufacturers live on the accruing saw dust, bark and wood shavings. These are freed from foreign objects, ground to a uniform size and meticulously dried before being made into small briquettes and then compacted.

Beware of too high humidity values

At the latest when tackling this step in the pellet manufacturing procedure one should be mindful of an optimum climate conditioning during operation. Because the pellets or wood chips, out of which the biofuel is compressed, have to be perfectly dry. Required is a maximum moisture content of 10 to 15 per cent! After all, wood is a sensitive natural resource that warps constantly. If too much moisture is withdrawn from the air, the formation of mould stains and mildew won't be long in coming. And both can render entire product batches unusable. Hence, when drying pellets, manufacturers should rely on modern technology constituting a reliable countermeasure to the humidity in the ambient air. In this respect Trotec is the ideal partner. For Trotec provides a suitable climate solution for all areas in the manufacturing of pellets: powerful, reliable and energy-efficient.

Reliable drying thanks to professional technology

The desiccant dehumidifiers of Trotec’s TTR series guarantee optimum climate conditions for pellet production and storage. They represent a high dehumidification performance even with low dew points. The powerful devices are available both for the mobile and stationary application. In either case: All models are extremely durable, require only little maintenance and can be configured flexibly. The industrial dehumidifiers of the TTR series are developed and manufactured according to the highest of quality standards in Germany. This means prime technology to meet the highest quality requirements for securing the production process and the products. Recommended for a permanent, steady dehumidification are especially the stationary dehumidifiers of the TTR series from Trotec. 

Economical permanent dehumidification

Extremely high capacities combined with an economic operation: That is the operating principle of the TTR desiccant dehumidifiers. They guarantee an effective permanent dehumidification during pellet production. When applied in the pellet warehouse, the devices also do a competent job and reliably protect the products from the formation of mould stains and mildew. The dry air volume can be adjusted steplessly, so the required climate values are achieved at the push of a button. The internal heat recycling process as well as the high level of resilience of the sorption rotors mean that the dehumidifiers of the TTR series are among the most economical dehumidifiers of their kind.
